I Application filed January '1, 1887. Serial No. 223,688. (No model.)

.T0 all whom iz'; may concrn:

Be it known that I, WILLIAM T. Davis, a

, citizen of the United States, residing at Battle vfication, Figure 1 is an elevation showing a broken portion of a Wiudow'and casing, with the catch attached to the sash, portion's of the sash and easing being in section, showing the bolt; Fig. 2, a view of the catch, showing the opposite side to that in Fig. 1; Fig. 3, a plate, below deseribed,and shown by dotted lines in Fig. 2; Fig. 4, a perspective view of the catchlever; and Fig. 5 is a perspective View of let tered details in Fig; 2.

Referring to the lettered parts of the drawings, B is the Vertical side piece of the sash, A the casing, andC the glass, of an ordinary Window.

The plate D, having a handle, c', is attached to the sash B, as in Fig. 1, and thesliding bolt E is inserted into the transverse hole through `the sash B and extends into a hole in the cas-.

ing A. The handled plate D is provided With a stud,f, forming a fulcrum to the lever R. (Other suitable means of fulcruming the lever may be adopted.) This lever somewhat resemblesv a bell-crank, the end a constituting the handle and the end a' engaging the end of the bolt E.

It will be observed that the bolt E has an open slot, u, loosely and detachably receiving the end a' of the lever B. By this means the vparts at u are readily coupled, and no especial care need be exereised in boring the bolt-hole, as the bolt E will adapt itself to slide in the hole without cramping, even if the hole is bored slanting or laterally out of place. Thus windows can be quickly'and in a practioal manner supplied with the catches without the need of askilled mechanic. Of course, in certain instances any practical manner of jointedly coupling the bolt E and lever R may be adopted. The end a' of the lever B flanges laterally, forming a stop to the upper end of the spring o, and the handle o' is flanged laterally from the plate D, forming a stop to hold the lower end of the spring o. This latter flange, together with the stud f, supports the plate P, Fig. 3. This plate P is detac-hably held in place by a screw passed through a hole in said plate and into a hole 'in the end of the studf, and by a projection, 2, on plate P, engaging a gain, 3, of the handle c', Figs. 3 and 5. The spring o is coiled around the stud f, Fig. 2, and the plate P covers the spring and holds it and the lever B on the stud f. The bolt is drawn ,by carrying the handle end a of the lever toward the handle c' of the plate D against a spring resistance. Thus when the lever R is released the spring throws thebolt to place.

The handle c' of the plate D is used toraise the window-or lower it while the thumb bears down on the handle a of thelever B, much the same in this respect as catches in car-windows.

The plate D has a lateral fiange, w, at the upper side, housing over the slotted end of the bolt E. The edge 4 of flange x and the end 5 of the handle-flange, Fig. 5, engage the inner edge of the sash B when the plate D is attached. Said engagement is not shown, but will appear evident from the drawings. i This obviatesundue strain on the screws which secure the catch to the sash B, Fig. 1.

In Figs. 2 and 5, 6 is a stop to limit the play of the lever R when thrown by the spring v after the handle a is released. Any equivalent spring may be employed.

It will be observed that the parts of this device are simple, easily made, and are all detachably connected; I am aware that sliding bolts operated by spring-actuated levers are not new, broadly considered; but so far as ice edge thereof, and having the fulermn-stnd and In testimony of the forogoing I have herero a handle provided with the lateral flange, a unto subsoribed my name in presenee of two level' fulernnled on said Stud and provided Witnesses.
